There is probably a good reason we don’t - it evolved out because we seem to be benefited by hiding our emotions
Though the causal link might be the other way around - if we were better with dealing with expressed emotion we could have kept the tail
Could probably look at the taxonomy to see when we lost it and what happened to our tailed brethren
Or it has little to do with emotions at all and more to do with physical changes based on environment.
True, prehensile tails are super useful for swinging around in trees
Other apes lost their tail as well, but they don’t hide their emotions.
Do you have a source for that?
Orangutan Jungle School.
I don’t see why we wouldn’t be able to control our tails, just as much as we can control our facial expressions.
